This is a little bit of a double post, but I know I just spent way too much time trying to get this figured out until I finally found the answer in the Bug-Hunt forum.
<Also requesting access to edit the Wiki so I can add this resolution / work around>
If you are trying to customize the DHCP scope (I.E. limit what IP addresses are handed out by the Almond+ fron DHCP) the wording on the configuration screens is wrong.
The DHCP server setting shows
1) Start Address: 100
2) Number of Leases : 150
3) DHCP Lease Time: 12h
What the text should actually be is:
1) Start Address: 100
2) End Address: 150
3) DHCP Lease Time: 12h
Basically if #1 is less than #2, DHCP will fail.
Looks like this will be fixed in a future update.
